i bought a car with a failed te45a turbo- sent it out to john craig for a rebuild-- i got new wheels, center section, all new bolts, and a BRAND NEW PTE .85 housing and everything LOOKS BRAND NEW- all this for $454.86
turn around was 1 week and i am very very pleased with their work-
the standard te45a is $1060.00 and another 250.00?? for the Q trim wheel-- call him and you will get all the answers you need

i just sent anoter turbo in for a rebuild- hope to get that one for next weeks project-
Go with the p-trim and 63 Precision housing. That is more turbo than any STREET car needs. Spool up should be good with your 9/11. That turbo should take you to almost any ET you are looking for. I ran 11 teens at 20 psi and a street chip.
does this turbo require that you use a IAC relocator???
damn Brian thats cookin...i see you best in your sig but what was your mph with street chip

i might just opt for that trim...:D

If you get a TE-45 (TE style compressor housing), no. I have a TC-45 (60-1 compressor housing with 4" inlet) and it pretty much required a relocator with ATR headers. A friend of mine has one with a 4 bolt adapter on stock headers and it moves his forward just enough to clear.
from what i've heard stick with a p-trim for a stock block and q-trim for stage. also heard a .63 housing is kinda a cork for a 45 and bigger turbo.
I don't consider my Garrett .63 housing a "cork"..... if one wanted to run higher boost levels (Stage motors), then maybe some inprovement could be seen with a bigger exhaust housing.....on a stock block, under 25 psi, the .63 is ideal...as is the "P" trim...ask John C. sometime...

remember, you are dealing with a turbo that can easily make enough power to destroy a stock block
I dont think it comes down to stock block or staged block as much as total air flow. The more air you flow the more BP you will have. At what point it starts to hurt you is when a change is needed.
My MPH was 120.8. That et was with a 1.58 60ft.
I think the 63 Precision housing is without question the best way to go. If you get into detail talking with John Craig. He may tell to you that the housing on that turbo is boarder line. That thing makes a good deal of power. An 85 might not hurt. But, I wouldn`t go any larger than the Precision 63. -IMO- Especially with a small cube motor.
im thinking precision .63 housing on my 3.8 but stepping up the a/r when my 4.1 motor is done.

i like the precision housing except for the fact that bolts dont come out of them without the threads coming with them but i have started using studs on everything to eliminate that problem.
